The Obama administration stymied a sprawling investigation into the terror group Hezbollah — and its highly lucrative drug- trafficking networks — to protect the Iran nuclear deal, according to a bombshell report.

A team at the Drug Enforcement Administration had been working for almost a decade to bring down the Iran-backed militant organization’s sophisticated $1 billion-a-year drug ring, which laundered money and smuggled cocaine into the United States, Politico reported.

But the departments of Justice and Treasury repeatedly undermined agents’ efforts to arrest and prosecute key members of the criminal network — because the Obama White House feared upsetting Tehran ahead of the nuclear agreement, according to Politico.

Hezbollah is an Iranian proxy, and Obama was more concerned about his political legacy than removing this most serious threat to Americans and our allies.
